Number of Siblings of a given node in n-arr tree

Number of Siblings of a given node in n-arr tree is simple if you keep it on paper. Amit uses it for folder on disk in a file explorer.

For Number of Siblings of a given node in n-arr tree, Big-O is in play. Don’t blame it until you have traced folder on disk.

Number of Siblings of a given node in n-arr tree exists so Amit can keep folder on disk correct in a file explorer.

Amit ships Number of Siblings of a given node in n-arr tree in a file explorer. That is the use case worth saying.

Number of Siblings of a given node in n-arr tree miss: unbalanced BST becoming a list. Fix it before you talk about advanced DSA.

After Number of Siblings of a given node in n-arr tree, Amit should still remember unbalanced BST becoming a list.

Close Number of Siblings of a given node in n-arr tree with: “If I skip it, folder on disk goes wrong like this: unbalanced BST becoming a list.”

Exam tip

Board: folder on disk. Dry-run Number of Siblings of a given node in n-arr tree. Name the trap: unbalanced BST becoming a list.

Example

# Number of Siblings of a given node in n-arr tree
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

Number of Siblings of a given node in n-arr tree: dry-run [4, 1, 3]. Say the list after one step.
